Abstract (en)
[origin: WO0017823A1] The invention relates to a method for verifying an authorization to log onto a system. According to the inventive method, a modified code is prestored in the system. Said modified code differs from the access authorization code stored in a part of the system which is inaccessible to or difficult to access by the user. Biological features of a user are detected and compared with features stored in the system. When said features coincide, a code is calculated from the modified code using a calculation specification. This calculated code is transmitted to the part of the system which is inaccessible to the user and is verified there using the stored access authorization code. The invention also relates to a device for verifying an access authorization to a system.
